It has been ascertained through test that this chemical or any of itssubstitutes willdecompose or deteriorate so as to be useless within afew months time unless the cartridge shell or container is lined withglass, and it is an object of this invention to provide a capsule orenvelope for the chemical which will be instantly destroyed as anentirety by the explosion of the shell in the gun, thereby avoiding thedecomposition or deterioration of the chemical within the shell of thecartridge in any such time or to materially The invention consists inthe novel con-' struction and combinations of parts as set forth in theappended claim.

In the accompanying drawing illustrating the invention:

Figure 1 is a central longitudinal section of the invention.

Figure 2 shows in perspective detail view tgellchemical container andthe cartridge s e Figure 3 is a cross section of the chemical container.

Figure 4 is a detail fragmentary view of one end of the chemicalcontainer 1n section.

In this drawing the numeral 1 designates an ordinary cartridge shellsuch as may be bought in the open market, and having the usualpercussion cap 2.

The tear gas chemical 3 before being placed in the cartridge shell isplaced within a container, envelop or ca sule 4 made of any suitablethin material of equal thinness throughout which will be atomizeddisintegrated or burned up at the moment 0 I discharge of the smallamount of black or smokeless powder 5 placed in the shell in rear of thechemical envelop as a propellant and to generate sufiicient heat in itsexplosion to immediately dedisc arge ofthe chemical from the cartridge,

the latter being intended for use in the tear gas gun of the co-pendingapplication of applicant. At the time of such discharge the chemical isof course dispersed forwardly over a wide area and particularl towardsthe object at which the gun is aime The chemical is placed in theenvelop preferably by machinery or afilling device of some kind beforethe envelop is placed in the primed shell, thereby avoiding hazard tothe workman filling the envelops. V

The envelo being sealed air tight, prevents the chemical rom coming incontact with the metal of the shell, which is one of the usual causes ofdeterioration. j

Among the materials of which the envelop may be made are cellulose, orrubber composition, impregnated paper, etc.

The sealing of the chemical within the container or envelop 4 may bedone in any suitable manner, such for lnstance as by the use of a topdisk 6 of the same material as that of the container, sealed around themar with cellulose acetate, parafiine or seahng wax.

I claim In a tear gas cartridge, having a primed shell, a propellant andheat eneratin filling for the inner end portion 0 said she and a.substantially complete filling for the entire outer end portion of saidshell consisting of a tear gas chemical and an envelope entirelysurrounding said chemical and composed of such readily combustiblematerial of such extreme thinness throughout that it will be immediatelyconsumed as an entirety at the moment of the explosion of the shell inthe whereof I aflix my signature.
